My tab-bar-tab-name-format-function causes 100% cpu spin as of ca3763af5c. Disabling tab-bar-auto-width fixes it.

Thanks for the bug report. Since with
(propertize " " 'display '(space :width (8))) the tab width can't grow more than 8 pixels,
a possible fix would be on every iteration
that adds more spaces to the tab name
to check if the tab width remains the same.
